The mosquitos that transmit Zika are generally daytime biters that do not travel significantly far from their hatching place.

I'd be more vigilant in sheltered mooring fields/anchorages with obvious mangrove breeding grounds, and less concerned ( if at all) when moored or anchored in a more open, exposed situation.

For EX: I'd be more careful in Biras Creek than I would at Cooper. I'd be more careful at Benures than I would at CGB. I'd choose to moor in the middle of the Bight than close to Water Point.

For me, after a day of sailing, swimming, and sun exposure, I tend to find comfort in a soft cotton long sleeve shirt and a pair of scrub pants on deck in the evenings. Without AC, you won't find me wearing those to sleep, but I do appreciate a port fan in my cabin which creates a " breeze" so I can be comfortable under the sheet.

We have mosquitos in Maine, they bite, and they can also transmit some not-lovelies like EEE and West Nile.

I don't like to get bit, either home or away.
